Letters Patent No. 108,155, dated October 11, 1870.

IMPROVEMENT IN SASH-HOLDERS.

The Schedule referred to in these Letters Patent and making'part of the same To all whom 'it may concern:

Beit known that I, GEORGE KING, of Frederick, inthe county of Frederick and State of Maryland, have invented an Improved Sash-Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification,.in which- Figure 1 is an elevation, showingr the improvement applied to parts of a widdow-sash and window-frame.

Figure 2 is an edge view ofthe portion of the sash shrliwn in iig. 1, with the look and part of the pendent roc Figure 3 is an inside view of the sash-lock, with part ofthe pendent rod attached.

Figure 4 is -an enlarged inside view of the sashlock, showing, by the aid of dotted lines, the gripingdog in two positions.

Figure 5 is a perspective view of the griping-dog.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to 'certain novel improvements on the sash-lock or fastening for which Letters Patent of the United States, numbered 90,558, were granted to me, bearing date on the 25th day of May, 1869.

The natureof my invention and improvement consists First, in constructing a metallic lock-case or frame,

adapted for receiving a loose griping-dog, with iiangesi on its back side, for receiving through them apendent rod, which is griped by said dog, and which is attached to the window-frame; also in constructing said case or frame with a rounded fulcrum-bearin g for the. gxipingdogg and, also, with a finger piece, which will afford a leverage to the fingers in operating the lock, as will be hereinafter explained.

Second, in the combination of a spring with the griping'dog, in such manner that this spring is inclosedin the same case with, and acts directly on, the dog, as will be hereinafter explained.

Third, in the combination of a griping-dog, which has a iingenpiece formed on its 'exposed end, with a pendent rod, which is pivoted at its upper end to the window-flame, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will describe `its construction and operation.

In the accompanying drawing I have represented, in fig. 1, portions of a window-frame, A, and a sash, B, having my improvements applied to them.

To the inside of the frame A, between the windowstrips a, and at a proper height, I pivot a rod, G, which is preferably round, and which is not attached to anything at its lower end. This peudenl rod is set oli` slightly from the face of the frame A, as indicated by dotted lines in ig. 1, and heilig pivoted at its upper end and free below, it may be swung inwardly whenthe inside strip a is removed'.

Both sides of the window-frame will be provided with the pendent rods, each one of which passes freely through holes which are made throughfianges g g', formed on their respectivelock-frames C.

I use a lock for both sides of a window-sash, and I employ the pendent rods so that the sash can be readily removed from them when desired.

The lock-case consists of a dat plate, C, which may be shaped as shown in the drawing, and which has flanges g y formed on its back side, through which the pendent rod G loosely passes. This plate C is perforated, to receive through it the screws that fasten it to the sash.

The ange g inclines from that edge of the plate C which lies contiguous to frame A, to a rounded enlargement, c, which affords a fulcrum or bearing for the griping-dog E, in the act of releasing this dog from its pendent rod G.

The iiange G forms two right angles, and its upper horizontal portion affords a support and stop for the dog E when the latter is adjusted in position to release the sash.

The lowerv horizontal portion of the flange g receives through it the rod G. On this plate is cast, or otherwise applied, a finger-piece, D, which affords a purchase to the lingers while in the act ot freeing the dog E from its rod, as indicated in iig. 1 by the dotted lines.

The dng E consists of a dat, narrow piece of metal,

perforated at f, and terminated at one end by a finger, l1. The hole f is circular, and slightly larger in diameter than the diameter of the rod G.

The finger-piece bis a little out of line with the body of the dog, so that, when the parts areall together, as shown in figs. l, 2, 3, and 4, this portion b will lie directly below the finger-piece D on the lockcase, on the face side thereof.

1When the dog E is iu the horizontal position indicated by the full lines in tig. 4, that is to say, when this dog is at right angles to the rod'G, the axis of the hole f will coincide with the axis of the rod G, and allow the sash to be either raised or lowered.

When this dog E is oblique to the rod G, as indicated by the dotted lines, lig. 4, this dog will gripe the rod and Iirmly hold the sash.

S is a helical spring, encircling the rod G, and compressed between the giiping end of the dog and the lower part of the ange g. This spring is thus inclosed in the case C, when applied to a sash, and will cause the dog to gripe the rod G when the finger piece b is not pressed upward.

2 Hoving described my invention, and dog E, constructed, arranged, andv operating snb- What I claim as new, and desire to secure by Letstnntally as described.

ters Patent, is 3. The pivoted pendent rod G, (free at its lower i 1.. The angular support g g of the-case C, and the end,) in combination with the spiral spring S, dog E,

rounded bearing c of the plate g', in combnatonwith and case C, substantially in the manner described.

the lever-dog E and finger-piece D, snbstnntially in Witnesses: GEORGE KING.
